Abstract
A plurality of first stations are linked with respective connectors which can be selectively activated to establish a signal path between any one of these stations and a second station via an intervening coupling network. Each connector includes at least one series switch between a pair of shunt switches, the former being closed while the latter are open in the activated state thereof. Selection is carried out with the aid of a control unit which, upon a switchover from one first station to another, sends a test signal through the hitherto active connector with successive reversals of its shunt and series switches and with measurement of the resulting impedances of that connector to determine its decoupling effect before activating the newly selected connector.
